Swapping between Hearth person and Peasant is currently the only way to "select" your starting town in Adventurer (it skips to the next random town each time until you get someplace close to where you want to be). Presumably that's no longer functional with the new background profession selection? Will you add a location selection to the new interface? Or do you prefer Adventurers to always start somewhere randomly within their selected civ?

Well, no vanilla entities currently host creatures with the [GOOD] tag, and I think there have been mentions of the possibilities of modding the spread of regional aspects before now. Might have been my wishful imagination though.

For the Myth and Magic Update, let's say there is a world where humans are created by a precursor race, and worship them. If another race, say the dwarves, are descendants of these precursor gods, will the humans revere dwarves, or generally be more prone to viewing them as religious figures? If humans are unaware of this mythic connection, but then they become aware of it, will their attitude concerning dwarves change?

[Regretfully, in my opinion, since this moves away from sandbox play and towards setting the world as opposition/problem to overcome - the great hero purging evil at the end of a sword or the great villain enthralling all who surround them (or perhaps we can find a safe little niche and avoid it... just maybe...). Or to put it positively how cool would it be to actively spread good and have demons, necromancers and other assorted nasties flee before waves of unicorns, sunshine and fluffy wamblers. But that would be another gaming paradigm, more along the lines of the player actively making the world...]

In the longer term it shouldn't matter since with the Myth and Magic update (coming soonTM) it is spheres that will be spreading (or not) and the old good and evil biomes will be defunct. Evil spreading is just the test case/initial prototype for all this (and Toady has probably accurately? judged the sorryness of the current crop of DF players before inflicting this upon us).

I personally kinda see good biomes in the same way as the Hallow from Terraria. It's the "good" equivalent, except its still not particularly good (I suppose a better way to describe it would be "fey") - its just as dangerous as the evil regions (atleast in Terraria, in DF, maybe not so much since the good regions are less fleshed out, unless you use mods), what with unicorns freely goring people to death and the like. So spreading good biomes would still not actually be the good thing to do.

Spreading good could get into a philosophical argument about how "good" it is to shoulder out indigenous varieties of plants and animals with good aligned versions as the sphere of influence grows.

I mean if there's always some potentional perverse benefit to doing so you might want to, supernaturally ideosyncratic 'demons of light' and other light magic associated entities like that being more of a annoyance than primordial unicorns are potentially. Some benefits like extension of your life for the longetivity sphere but the areas being patrolled by bloodthirsty magical sentinels.

Will there be sphere created semi/mega-beasts where appropriate emerging with the wildlife (within world costing), or will they always be resorted to world generation?

I was kind of hoping to have a greater muck monster for the evil biomes pop up when the conditions were right, or inversely to the quotation, maybe a Phoenix spontaneously appear over rebirth good areas to add some danger setting things on fire with the halves of a roc and a dragon together.

Without a proper reply from Toady, until its all sorted out, i think evil biomes as they are will just be 'Primordial' until least after the changes to world generation are put in and a clean slate to make the world as they want it. But i mirror your opinion that spreading good biomes at this stage doesn't really have a purpose outside of being there for modders.

Potentially some interaction with angel vaults or shrines I abstractly think of having a higher potential chance of hosting some couter or alternative influence but thats just my own speculation.
